Description

Ultrasonic ceramic transducers transfer acoustical energy to

mechanical energy or vice versa. The Standard Open Type

Transducer is constructed in a manner which incorporates the

fundamental structure of piezoelectric ceramic element of the

monomorph type with a conical metal resonator. This Special

combination provides high sensitivity (Over – G5dB/V/µBar),

wider bandwidth, excellent temperature and humidity durability,

stable electrical and mechanical characteristics, and small size.

Applications:

• Remote control devices

• Liquid & bulk sensors

• Level controls

• Intrusion alarms

• Motion detectors

• Auto doors

• Counting devices
